Issue/Introduction

We have observed that interface groups are not getting refreshed as per the group definition filters.

New devices are discovered, but the groups don't reflect them.

Deactivating and activating udm_manager seems to restore the functionality temporarily.

Environment

Release : 20.3

Component :

Resolution

In many environments, the default settings for udm_manager are too conservative and will cause the probe to struggle to populate interface/inventory data.

Using Raw Configure you should set the values for udm_manager to be as follows -- any configuration key which is not present in your current config should be added as seen below.

 

The following represents our current "best practice" configuration and in a future update these will be the default settings for udm_manager:

<setup>
   loglevel = 3
   logfile = udm_manager.log
   logsize = 5000
   host =
   schema_connection_timeout_minutes = 30
   schema_transact_retries = 5000
   <datomic>
      port = 4334
      memory_index_max = 512m
      memory_index_threshold = 64m
      object_cache_max = 256m
   </datomic>
</setup>
<startup>
   <opt>
      java_mem_init = -Xms1024m
      java_mem_max = -Xmx2048m
      java_opts = -server -XX:ErrorFile=./hs_err_pid.log -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode
   </opt>
</startup>
